## Unit0.1.1Welcome to LAFF-On Programming for High Performance

These notes were written for a Massive Open Online Course (MOOC) that is offered on the edX platform. The first offering of this course starts on June 5, 2019 at 00:00 UTC (which is late afternoon or early evening on June 4 in the US). This course can be audited for free or you can sign up for a Verified Certificate. Registers at https://www.edx.org/course/laff-on-programming-for-high-performance.

While these notes incorporate all the materials available as part of the course on edX, being enrolled there has the following benefits:

• It gives you access to videos with more convenient transcripts. They are to the side so they don't overwrite material and you can click on a sentence in the transcript to move the video to the corresponding point in the video.

• You can interact with us and the other learners on the discussion forum.

• You can more easily track your progress through the exercises.

Most importantly: you will be part of a community of learners that is also studying this subject.
